I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to provide an additional means to access its 
Member Firm Portal (described below).

[[Page 46289]]

    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://www.miaxglobal.com/markets/us-options/all-options-exchanges/rule-filings">https://www.miaxglobal.com/markets/us-options/all-options-exchanges/rule-filings</a>, and at the Exchange's principal office.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange provides Members \3\ access to an internet-facing 
portal which provides self-service functions to Members, known as the 
Member Firm Portal (``MFP'').\4\ Specifically, the MFP allows Members 
to correct certain trade information required by the Options Clearing 
Corporation (``OCC''), such as the trade's account number, sub-account 
number, Clearing Member Trade Assignment (``CMTA''), Clearing 
Participant Give-Up, or account type. The MFP also provides Members the 
ability to adjust risk settings and allows Market Makers \5\ to request 
options class assignments. Members may also perform the following 
functions via the MFP: selecting symbol assignments; editing existing 
symbol assignments; unassigning one or more symbols; retrieving symbol 
assignments; receiving export of symbol assignments for a business day; 
and retrieving assignment history for a given symbol assignment. The 
MFP allows Members to more efficiently manage their back office 
operations and assist them in providing accurate clearing information 
to the OCC. Currently, access to the MFP is provided on a per user 
basis, whereby Members seek to have individuals within their 
organization permissioned to access the MFP via a web portal on their 
behalf (known as the ``MFP User Interface'' or ``MFP UI''). The 
Exchange notes that other options exchanges make similar products 
available to firms for a monthly per user fee.\6\ The Exchange provides 
the MFP UI to Members for free.
---------------------------------------------------------------------------

    \3\ See Exchange Rule 100.
    \4\ See MIAX Sapphire Options Exchange User Manual, Version 
1.1.0 (revision date July 9, 2025), available at <a href="https://www.miaxglobal.com/miax_sapphire_user_manual.pdf">https://www.miaxglobal.com/miax_sapphire_user_manual.pdf</a>. See also MIAX

    \5\ See Exchange Rule 100.
    \6\ See BOX Exchange LLC Fee Schedule, Section III. D., Trade 
Management System (assessing a fee of $350 per month, per user); The 
Nasdaq Stock Market LLC (``Nasdaq'') charges $200 per month, per 
user. See Nasdaq Rules Options 7 Pricing Schedule, Section 6, Nasdaq 
Options Maintenance Tool. See also Securities Exchange Act Release 
No. 96723 (January 20, 2023), 88 FR 5046 (January 26, 2023) (SR-BOX-
2023-03) (Notice of Filing and Immediate Effectiveness of a Proposed 
Rule Change to Establish a New Service and Related Fees for Use of 
the BOX Options Market LLC (``BOX'') Trade Management System).
---------------------------------------------------------------------------

    Members may also access the MFP via an Application Programming 
Interface \7\ (``API'' and together ``MFP API''), in addition to the 
current MFP UI accessed via the web portal. In sum, an API is a way for 
two or more computer programs to talk to each other. It is a software 
to software interface that defines the data and the transactions that 
can be communicated between systems. In providing the MFP API, 
functions that would otherwise be done manually via the MFP UI, can be 
automated. The MFP API, in essence, facilitates and expedites the 
transaction processing for the supported functionality such that 
Exchange Members can automate their interactions with the MFP. This 
allows for more efficient processing, the potential reduction of 
operational risk due to issues caused by human error, and the 
timeliness of the completion of MFP-related functions.\8\ Providing API 
access to the MFP would allow Members to enable their systems and 
applications to communicate directly with the MFP, thereby eliminating 
or reducing the need for individuals to access the MFP UI via the web 
portal.
---------------------------------------------------------------------------

    \7\ If the Exchange determines to propose fees for API access to 
the MFP, the Exchange will submit a separate filing with the U.S. 
Securities and Exchange Commission pursuant to Section 19(b)(1) to 
propose such fees.
    \8\ See, e.g., What is an API?, available at <a href="https://www.ibm.com/topics/api">https://www.ibm.com/topics/api</a> (last visited August 27, 2025).
---------------------------------------------------------------------------

    The Exchange does not propose to alter the current MFP or MFP UI. 
The Exchange simply proposes to provide an additional and optional 
means to access the MFP, in the form of an API, and Members would be 
able to perform the same functions they do today when they access the 
MFP UI via the web portal. API access to the MFP would allow a Member's 
applications to communicate directly with the MFP. Therefore, by its 
nature, the MFP API does not lend itself to access on a per user basis, 
as is the case today with the MFP UI via the web portal. API access 
would allow Members to automate functions they perform today on the 
MFP, such as adjusting risk settings or managing options assignments. 
Members who do not prefer to access the MFP API would be able to 
perform the same functions when accessing the MFP UI via the current 
web portal.
    The Exchange notes that use of accessing the MFP API would be 
completely voluntary and would simply be second optional means to 
access the MFP. Members who wish to continue to access the MFP UI via 
the web portal may continue to do so for no fee. The Exchange's 
affiliates, Miami International Securities Exchange, LLC (``MIAX''), 
MIAX PEARL, LLC (``MIAX Pearl''), and MIAX Emerald, LLC (``MIAX 
Emerald''), previously filed to provide their members with the ability 
to access the MFP via an API.\9\
---------------------------------------------------------------------------

    \9\ See Securities Exchange Act Release Nos. 98016 (July 28, 
2023), 88 FR 51364 (August 3, 2023) (SR-PEARL-2023-32); 98018 (July 
28, 2023), 88 FR 51374 (August 3, 2023) (SR-EMERALD-2023-18); and 
98017 (July 28, 2023), 88 FR 51366 (August 3, 2023) (SR-MIAX-2023-
29).
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the requirements of Section 6(b) of the Act,\10\ in general, and 
Section 6(b)(5),\11\ in particular, because it is designed to prevent 
fraudulent and manipulative acts and practices, to promote just and 
equitable principles of trade, to foster cooperation and coordination 
with persons engaged in regulating, clearing, settling, processing 
information with respect to, and facilitating transactions in 
securities, and to remove impediments to and perfect the mechanism of a 
free and open market and a national market system.
---------------------------------------------------------------------------

    \10\ 15 U.S.C. 78f(b).
    \11\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange notes that providing the MFP API to Members is 
consistent with the Act in that the use of MFP API is completely 
voluntary and simply provides Members with an additional means to 
access the Exchange's MFP. The MFP is a useful tool for Members to 
manage their trading on the Exchange, including back office operations, 
risk controls settings, and Market Maker options assignments.
    As noted above, accessing the MFP via an API would be an optional 
alternative to web access. Those not electing to access the MFP via an 
API may continue to use the MFP UI via the web portal free of charge. 
The MFP, whether accessed via an API or web

[[Page 46290]]

portal, allow Members to more efficiently manage their back office 
operations, assist them in providing accurate clearing information to 
the OCC and in selecting Market Maker options assignments. The Exchange 
notes that trade information in the MFP is specific to each Member and 
their trades, allowing them to conveniently verify, update, and/or 
correct transaction information as needed.
    Providing API access to the MFP would be provided purely for 
convenience, in response to Member demand, and would be entirely 
optional. As stated above, API access to the MFP would enable Members 
to connect their applications to the MFP allowing their application to 
communicate directly with the MFP. This enables Members to automate 
functions that would normally be performed by individual users access 
the MFP via the current web portal, such as adjusting risk settings and 
managing options assignements. Members who do not prefer to access the 
MFP API would be able to perform the same functions by accessing the 
MFP UI via the existing web portal.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
result in any burden on competition that is not necessary or 
appropriate in furtherance of the purposes of the Act. API access to 
the MFP would simply be an optional additional means to access the MFP. 
The Exchange does not believe there would be any competitive advantage 
for Members who access the MFP via an API over those who access it via 
the current web portal because Members would be able to perform the 
same functions via both modes of access. API access would simply be a 
convenience and would enable Members to automate those functions. The 
Exchange does not believe a Member's ability to automate this 
functionality provides any competitive advantage when trading on the 
Exchange. As such, the Exchange does not believe that the proposed rule 
change will impose any burden on intermarket or intramarket competition 
not necessary or appropriate in furtherance of the purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    Written comments were neither solicited nor received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    The Exchange has filed the proposed rule change pursuant to Section 
19(b)(3)(A) of the Act \12\ and Rule 19b-4(f)(6) \13\ thereunder. 
Because the foregoing proposed rule change does not: (i) significantly 
affect the protection of investors or the public interest; (ii) impose 
any significant burden on competition; and (iii) become operative for 
30 days from the date on which it was filed, or such shorter time as 
the Commission may designate, it has become effective pursuant to 
Section 19(b)(3)(A) of the Act \14\ and Rule 19b-4(f)(6) \15\ 
thereunder.
---------------------------------------------------------------------------

    \12\ 15 U.S.C. 78s(b)(3)(A).
    \13\ 17 CFR 240.19b-4(f)(6).
    \14\ 15 U.S.C. 78s(b)(3)(A).
    \15\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change, along 
with a brief description and text of the proposed rule change, at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \16\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b4(f)(6)(iii),\17\ the Commission 
may designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange has asked 
the Commission to waive the 30-day operative delay so that the proposed 
rule change may become operative immediately upon filing. The Exchange 
states that it currently provides web-based access to the MFP free of 
charge and, while Members who access the MFP via an API would be able 
to automate certain functions, Members would be able to perform the 
same functions in the MFP regardless of whether they access the MFP via 
the web portal or an API. The Exchange also states that waiver of the 
operative delay would allow the Exchange to expand the means of access 
to the MFP sooner and allow Members to meet their own back office 
needs. In addition, the Exchange's affiliates previously filed to 
provide their members with the ability to access the MFP via an 
API.\18\ For these reasons, and because the proposed rule change does 
not raise any novel legal or regulatory issues, the Commission finds 
that waiver of the 30-day operative delay is consistent with the 
protection of investors and the public interest. Therefore, the 
Commission hereby waives the 30-day operative delay and designates the 
proposed rule change to be operative upon filing.\19\

    \17\ 17 CFR 240.19b-4(f)(6)(iii).
    \18\ See supra note 9.
    \19\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission shall institute proceedings to 
determine whether the proposed rule should be approved or disapproved.
